In Singapore's hot and humid climate, watercolor papers are particularly prone to a paper oxidation issue known as foxing, which refers to the discoloration forming yellowish-brown stains on paper, changing the visual outcome of the watercolor artworks. This research investigates two most popular types of watercolor paper, made from 100% cotton and cotton-wood-pulp mixture. Foxing was generally categorized into two types: biotic and abiotic foxing caused by fungi activities and the presence of metallic contaminants catalytic fungi growth.

Single-atom-based Metal-Organic Frameworks (MOFs) hold great promising candidates for heterogeneous catalysis, demonstrating outstanding catalytic activity and exceptional product selectivity. This is attributed to their optimal atom utilization, high surface energy, and the presence of unsaturated coordination environments. Here in, we have developed a nickel single-atom catalyst (UiO-66/Ni) featuring Ni single atoms covalently attached to defect-engineered Zr-oxide clusters within the stable UiO-66 framework, synthesized via a straightforward solution impregnation method.

Introduction: Lung injury, a common complication of sepsis, arises from elevated reactive oxygen species (ROS), mitochondrial dysfunction, and cell death driven by inflammation. In this study, a novel class of ultrasmall nanoparticles (CuO USNPs) was developed to address sepsis-induced lung injury (SILI).
Methods: The synthesized nanoparticles were thoroughly characterized to assess their properties.

Background: Rapid industrialization globally has led to a notable increase in the production and utilization of metals, including cadmium (Cd), consequently escalating global metal pollution worldwide. Cd, characterized as a persistent environmental contaminant, poses significant health risks, particularly impacting human health, notably the functionality of the kidneys. The profound effects of Cd stem primarily from its limited excretion capabilities and extended half-life within the human body.

The effect of a citrus-derived flavonoid, hesperetin, on the automaticity and contraction of isolated guinea pig myocardium was examined. Hesperetin inhibited the rate of ectopic action potential firing of the pulmonary vein myocardium; the slope of the diastolic depolarization was decreased with minimum change in the action potential waveform. The effect was dependent on the concentration; the EC value for firing rate was 56.
